Convert an alarm clock (that is only battery powered) to use AC power? Possible?

Is it possible to convert an alarm clock (that is only battery powered) to use AC power so that I can plug it in? If so, can you provide instructions?

Given the cost of an alarm clock it would probably be cheaper to buy one meant for 120 volts.

Are you using that many batteries?

Actually, I just read that is has a "transformer jack". Do you believe they mean a jack to plug in an AC power adapter?

I've attached an illustration they provided ...

By reading those instructions it looks like that the clock doesn't even have a Jack to plug in a power supply. You would either have to install a Jack or where the transformer directly into the unit itself. As stated earlier in this thread you would be further ahead buying a new alarm clock as far as cost and aggravation goes

Sounds like you can use a wall wart power supply.

A wall wart power supply? Can you elaborate?

And I want this clock because it has sentimental value (plus, a Super Mario Galaxy design).

That would be 6 volts if in series. 6 volt (500ma or larger) DC wall warts are common. You probably have a couple in your junk drawer if your like me. In a case like this I substitute wood dowels for the batteries and a screw on the end with a wire from the wall wart to supply the voltage. If you post a picture of the battery compartment (batteries removed) I can be more specific. Note my way does not require opening the clock or making any changes or permanent connections.
